如果解析嵌套多层的JSON数据？

Question

    var dataDemo = [
        {name: "订单处理", level:1 ,children:[
            {name: "所有订单", level:2},
            {name: "待付款", level:2, children:[
                {name: "锁定及撤销出库", level: 3}
            ]},
            {name: "待发货", level:2, children:[
                {name: "填写发货单", level: 3},
                {name: "修改发货单", level: 3},
                {name: "下载发货单", level: 3},
            ]},
            {name: "待收货", level:2},
            {name: "已收货", level:2},
        ]}
    ]

如上面贴上的json数据，目前我写的只有三层，我现在的做法是写三个嵌套for去解析处理，假设数据超过三层的时候我该怎么写？嵌套写for也很乱

    var dataDemo = [
        {name: "订单处理", level:1 ,children:[
            {name: "所有订单", level:2},
            {name: "待付款", level:2, children:[
                {name: "锁定及撤销出库", level: 3}
            ]},
            {name: "待发货", level:2, children:[
                {name: "填写发货单", level: 3},
                {name: "修改发货单", level: 3},
                {name: "下载发货单", level: 3},
            ]},
            {name: "待收货", level:2},
            {name: "已收货", level:2},
        ]}
    ]

    let parse = arr => {
        arr.forEach(item => {
            // do some ...
            console.log('item: ', item)
            
            if (Array.isArray(item.children)) {
                parse(item.children)
            }
        })
    }

    parse(dataDemo)
